Problems solved by technology

[0005] The content and order of each operation step in the electronic security ticket is fixed, which cannot meet the requirements for secondary safety measures in different operating environments on site, cannot adapt to the operation and maintenance habits of different regions, and requires high professional quality of operation and maintenance personnel. Promotion difficult to implement;
[0006] The verification of the implementation status of safety measures can only be limited to the verification and confirmation of the steps in a single safety measure ticket, and the verification of the relationship between safety measures between the maintenance interval and the associated operation interval cannot be realized; and this verification method relies on Due to the specific security measures, online real-time verification cannot be realized;
[0007] There are many kinds of security measures in the whole station, the compilation is complicated, and there is a lack of effective management and control means

Abstract

The invention discloses an intelligent substation maintenance safety measure execution state checking method and a device. The method comprises the following steps: acquiring states of a primary switch, a knife switch and a grounding wire of an intelligent substation, and running state information and soft and hard pressing plate state information of relay protection equipment, and analyzing to obtain an actual primary interval state and an actual secondary equipment state of the relay protection equipment; obtaining a safety measure requirement of an actual maintenance work scene of the intelligent substation to obtain a safety measure task; according to the safety measure task, in combination with a pre-constructed safety measure checking rule expert knowledge base based on the safety measure task and the primary and secondary equipment states, performing analysis to obtain a corresponding standard primary interval state and a standard secondary equipment state; comparing the actualprimary interval state with the standard primary interval state, and comparing the actual secondary equipment state with the standard secondary equipment state to obtain a check result; and outputtingcheck results. And checking of the execution state of the safety measure task of the intelligent substation is realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent operation inspection for relay protection of electric power systems, and in particular relates to a method and device for checking the execution status of safety measures for intelligent substation maintenance. Background technique [0002] In traditional substations, the safety measures for the secondary circuit follow the principle of "should have an obvious disconnection point". It can ensure that the equipment will not accidentally move the exit. However, there is a big difference between the smart substation and the traditional substation. The smart substation uses optical fiber as the medium to realize data transmission, and the interconnection between devices becomes an optical fiber communication link. The form is called "virtual circuit" and "soft pressure plate". In the eyes of operation and maintenance personnel, a substation that can be operated and detected has changed from "real...
